Questions about the behavior of the ACO parameter DisableDNSLookup:
With DisableDNSLookup set to NO, does the Web Agent do a Reverse DNS Lookup when it receives a request with an IP Address instead of a Fully Qualified Domain Name in the URL?
When DisableDNSLookup is set to NO, how does the Web Agent do the reverse DNS Lookup?
Does DisableDNSLookup disable forward DNS Lookup too, as requesting the IP Address from the FQDN?
Yes, it does.
And this is to prevent the behavior that the DisableDNSLookup=YES will disable these reverse DNS requests.
